Above is a link to a interactive website and video that gives a bit of information on cyber-bullying. During my psychology degree, I spent some time looking at cyber-bullying and how it effects people, particularly younger people (here, I'm saying between the ages of about 12 to 26). I have seen these sorts of things happen to friends, people I know, or people I have had passing interactions with, and I have never liked them.
If someone puts a photo of themselves up that they find funny, okay sure. But if it's of someone else and they don't know what you're doing? Or if you comment on someone's photo or facebook in a negative way - even if you think 'it was just a joke' - it can be really hurtful. This is part of the reason why I don't have a facebook - aside from it's time-sucking habits.
Please have a look. I know many people who are beautiful souls that wouldn't hurt a fly, but perhaps there's someone you know that could benefit from this?
Love to all who read.
